$\int_{-1}^{3} x^2dx+\int_{-1}^{3}-2xdx+\int_{-1}^{3}1dx$
Learn how to solve definite integrals problems step by step online. Integrate the function x^2-2x+1 from -1 to 3. Expand the integral \int_{-1}^{3}\left(x^2-2x+1\right)dx into 3 integrals using the sum rule for integrals, to then solve each integral separately. The integral \int_{-1}^{3} x^2dx results in: \frac{28}{3}. The integral \int_{-1}^{3}-2xdx results in: -8. The integral \int_{-1}^{3}1dx results in: 4.
